## API Documentation

### Base URL
All API requests should be made to: `https://prod.api.market/api/v1/torquenode/license-plate-lookup`

### Authentication
Authentication is handled via API key. Include your API key in the request header as `x-api-market-key`:
```
x-api-market-key: YOUR_API_MARKET_KEY
```

### Endpoints

This API utilizes a single, synchronous endpoint to retrieve vehicle data instantly.

#### License Plate Decode
`GET /api/v1/torquenode/license-plate-lookup/license-decode`

Submit a license plate lookup request via query parameters. The API will process this request and return the vehicle data in the immediate response.

**Query Parameters**

| Parameter | Type   | Required | Description                                                    | Example     |
| :-------- | :----- | :------- | :------------------------------------------------------------- | :---------- |
| `plate`   | string | Required | The license plate number to look up.                           | `3204518`   |
| `state`   | string | Required | The U.S. state (2-letter code) of the license plate.           | `IN`        |

**Example Request**

```bash
curl -X GET "https://prod.api.market/api/v1/torquenode/license-plate-lookup/license-decode?plate=3204518&state=IN" \
  -H "x-api-market-key: YOUR_API_MARKET_KEY"
```

**Example Response (200 OK - Succeeded)**
Upon successful lookup, the API returns the vehicle data directly.

```json
{
    "status": "success",
    "data": {
        "vin": "3AKJHLDV1PSNH7027",
        "year": "2023",
        "make": "Freightliner",
        "model": "Cascadia",
        "plate": "3204518",
        "state": "IN"
    }
}
```

## Status Codes
A comprehensive list of HTTP status codes and their meanings:

*   **200 OK**: Request successful. The response will contain the vehicle data.
*   **400 Bad Request**: Invalid input parameters or malformed request. Check your query parameters for correctness (e.g., missing `plate` or `state`).
*   **401 Unauthorized**: Missing or invalid API key. Ensure your `x-api-market-key` header is present and contains a valid key.
*   **403 Forbidden**: Valid API key but insufficient permissions to perform the action.
*   **404 Not Found**: Data for the requested license plate and state could not be found. 
*   **429 Too Many Requests**: Rate limit exceeded. You are sending too many requests in a given time frame. Implement exponential backoff or wait before retrying.
*   **500 Internal Server Error**: A server-side error occurred. This is typically not due to your request but an issue on the API provider's end. It's advisable to retry after a short delay.
*   **503 Service Unavailable**: The service is temporarily unavailable, usually due to maintenance or overload. Retry your request after some time.

## Rate Limits
Specific rate limits are enforced to ensure fair usage and system stability. If you exceed the rate limits, you will receive a `429 Too Many Requests` status code. It is recommended to implement an exponential backoff strategy for retries to avoid continuous rate limit breaches. For higher throughput needs, consider upgrading your pricing tier.

## Error Handling
Effective error handling is crucial for robust API integration.

*   **Interpret Error Responses**: When an error occurs (e.g., non-2xx status code), the API will typically return a JSON object with details about the error.
*   **Common Errors**:
    *   `400 Bad Request`: Often caused by missing required query parameters (`plate`, `state`). Review your request URL.
    *   `401 Unauthorized`: Always check your `x-api-market-key`. It might be missing, expired, or incorrect.
    *   `404 Not Found`: The API could not find vehicle data associated with the provided license plate and state combination.
*   **Retry Strategies**: For transient errors (`500`, `503`, `429`), implement a retry mechanism with exponential backoff. This means increasing the delay between retries over time to avoid overwhelming the server. For non-transient errors (`400`, `401`, `403`, `404`), retrying without modifying the request is usually fruitless.

## Implementation Guide

This guide provides examples for integrating the synchronous License Plate Lookup API.

### Example Code

#### JavaScript Example

This example demonstrates how to retrieve vehicle data using `fetch`.

```javascript
const apiKey = "YOUR_API_MARKET_KEY";
const baseUrl = "https://prod.api.market/api/v1/torquenode/license-plate-lookup";

async function getVehicleData(plate, state) {
  try {
    const url = new URL(`${baseUrl}/license-decode`);
    url.searchParams.append('plate', plate);
    url.searchParams.append('state', state);

    const response = await fetch(url, {
      method: "GET",
      headers: {
        "x-api-market-key": apiKey
      }
    });
    
    if (!response.ok) {
      const errorBody = await response.json().catch(() => ({}));
      throw new Error(`API error: ${response.status} ${response.statusText} - ${JSON.stringify(errorBody)}`);
    }
    
    const result = await response.json();
    return result.data;
  } catch (error) {
    console.error("Error retrieving vehicle data:", error);
    throw error;
  }
}

// Example usage:
(async () => {
  try {
    const vehicleData = await getVehicleData("3204518", "IN");
    console.log("Retrieved vehicle data:", vehicleData);
  } catch (error) {
    console.error("Failed to retrieve vehicle data.");
  }
})();
```

#### Python Example

This Python example uses the `requests` library to handle the GET request effortlessly.

```python
import requests
import json

API_KEY = "YOUR_API_MARKET_KEY"
BASE_URL = "https://prod.api.market/api/v1/torquenode/license-plate-lookup"

def get_vehicle_data(plate, state):
    headers = {
        "x-api-market-key": API_KEY
    }
    
    params = {
        "plate": plate,
        "state": state
    }
    
    response = requests.get(
        f"{BASE_URL}/license-decode",
        headers=headers,
        params=params
    )
    
    if response.status_code != 200:
        raise Exception(f"API error: {response.status_code} {response.text}")
    
    result = response.json()
    return result.get("data")

# Example usage:
if __name__ == "__main__":
    try:
        vehicle_data = get_vehicle_data("3204518", "IN")
        print("Retrieved vehicle data:")
        print(json.dumps(vehicle_data, indent=2))
    except Exception as e:
        print(f"Failed to retrieve vehicle data. Error: {e}")
```

#### cURL Example

A simple one-line cURL command to get the data instantly.

```bash
# cURL example
# Replace YOUR_API_MARKET_KEY with your actual API key.

curl -X GET "https://prod.api.market/api/v1/torquenode/license-plate-lookup/license-decode?plate=3204518&state=IN" \
  -H "x-api-market-key: YOUR_API_MARKET_KEY"
```

### Performance Optimization
*   **Connection Reuse**: When making multiple API requests, use HTTP Keep-Alive (standard in most modern HTTP clients like `requests` in Python or `fetch` in Node.js) to reuse TCP connections, reducing latency.
*   **Parallel Requests**: Because this API is synchronous and fast, if you have a batch of license plates to process, you can fire off requests concurrently (using `Promise.all` in JS, or ThreadPoolExecutor in Python) to drastically decrease overall processing time. Always ensure you stay within your rate limits.

## FAQ
*   **What is a VIN?**
    The Vehicle Identification Number (VIN) is a unique 17-character code used to identify individual vehicles. It encodes information about the manufacturer, year, model, and specific characteristics of the vehicle.
*   **What vehicle information can I retrieve?**
    You can retrieve the VIN, make, model, and year of the vehicle associated with the license plate.
*   **Which U.S. states are supported?**
    The API supports license plate lookups for all U.S. states.
*   **What happens if a license plate is not found?**
    If the license plate is not found or is invalid for the specified state, the API will return an error (typically `404 Not Found`).
*   **Is the API synchronous or asynchronous?**
    This API is completely **synchronous**. You simply make one GET request and receive the full vehicle data back in the immediate response—no polling required.
